Photoelectric conversion device, information processing device, method for controlling photoelectric conversion device, and information processing method

An information processing device comprising:

• a detection unit configured to generate pixel information indicating that a pixel does not satisfy a predetermined criterion when it is detected that the pixel does not satisfy the predetermined criterion by using a first signal corresponding to an amount of light incident on the pixel in a first accumulation period;
• and
• a correction unit configured to correct a second signal corresponding to an amount of light incident on the pixel in a second accumulation period including the first accumulation period and a period after the first accumulation period based on the pixel information,
• wherein the detection unit acquires the first signal during a period from an end of the first accumulation period to an end of the second accumulation period, and
• wherein the correction unit acquires the second signal after the end of the second accumulation period.

A method for controlling a photoelectric conversion device including a pixel configured to generate a signal corresponding to an amount of incident light, a memory configured to hold the signal, and a processing unit configured to perform signal processing based on the signal held in the memory, the method comprising:

• generating, by the pixel, the signal in a second accumulation period including a first accumulation period and a period after the first accumulation period;
• acquiring, by the processing unit, a first signal corresponding to an amount of incident light in the first accumulation period from the memory in a period from an end of the first accumulation period to an end of the second accumulation period;
• generating, by the processing unit, pixel information indicating that a pixel does not satisfy a predetermined criterion when it is detected that the pixel does not satisfy the predetermined criterion by using the first signal;
• acquiring, by the processing unit, a second signal corresponding to an amount of incident light in the second accumulation period from the memory after the end of the second accumulation period;
• and
• correcting, by the processing unit, the second signal based on the pixel information.

An information processing method comprising:

• generating abnormal pixel information indicating an abnormal pixel detection result based on a first signal corresponding to an amount of light incident on a pixel in a first accumulation period;
• and
• correcting a second signal corresponding to an amount of light incident on the pixel in a second accumulation period including the first accumulation period and a period after the first accumulation period based on the abnormal pixel information,
• wherein the first signal is acquired during a period from an end of the first accumulation period to an end of the second accumulation period, and
• wherein the second signal is acquired after the end of the second accumulation period.
